Legal Frameworks for Policing Crowds

This chapter examines the legal foundations of freedom of assembly and expression and their implications for policing crowds in democratic societies. Opening with the 1968 Democratic National Convention, it illustrates the dangers when rights protections are absent and police power overwhelms safeguards. It then traces the evolution of international and regional instruments – the Universal Declaration of Human Rights (1948), International Covenant on Civil and Political Rights (1966), and European Convention on Human Rights (1950) – and shows how these shape European protections, incorporated into UK law through the Human Rights Act (1998) but constrained by statutes such as the Public Order Acts of 1936, 1986, and 2023. By contrast, the United States relies on constitutional protections in the First, Fourth, and Fourteenth Amendments, elaborated through doctrines of time, place, and manner restrictions, forum analysis, and litigation, alongside state-level offences such as unlawful assembly. This chapter maps how rights and powers are codified, enforced, and contested, noting proportionality in Europe and reasonableness in the U.S. as parallel but fragile standards. Controversies over kettling, stop-and-search, mass arrests, and less-lethal weapons highlight how courts alternately reinforce or dilute protections. This chapter concludes that how police navigate these frameworks profoundly shapes rights protection, public order management, and the legitimacy of democracy itself.
